GAS-STOVE BU R-N ER.

SPECIFICATION forming part of Letters Patent No. 593,623, dated November 16, 1897.

I Application filed February 4, 1897. vSerial No. 621,913- v (No model.) i

To all whom it may concern.-

Be it known that I, MARTIN A. THIEL, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Gas-Stove Burners, of which the following is a description, reference being had to the accompanying drawings, which are a partrof this specification.

My invention has relation to improvements in gas-stove burners.

The primary object is to provide a burner of such form that all the interior parts may be readily accessible for cleaning purposes.

A further object resides in the economical feature of the device, the construction being such that perfect combustion is secured and also a burner provided perfectly free from joints,whereby the escape of gas is prevented.

With the above and other incidental objects in view the invention consists of the devices and parts, or their equivalents. as hereinafter more fully set forth.

' In the accompanying drawings, Figure 1 is a plan view of the complete burner with a part of the top broken away. Fig. 2 is a central I indicates a cup-shaped chamber, advisably of the usual annular form and provided with a tubular interiorly-threaded inlet extension 5, adapted to be connected to the pipe which supplies gas to the chamber. 7

The upper portion of the burner is provided with an opening 6 entirely around the same,

the bordering edges of said opening being upright or vertical, and in the bottom of the chamber is a groove 7, preferably extending entirely around the chamber.

The numeral 8 indicates a removable cappiece which is adapted to fit the opening 6 of the chamber, with its upper surface preferably fiush with the corresponding surface of said chamber. This cap-piece is advisably of a substantial V shape in cross-section, the V-shaped portion projecting down into the chamber for a desired distance and being formed with a plurality of depending legs 9, which are preferably beveled or pointed at their lower ends to fit the shape of the groove 7. It will be noticed that the cap-piece does not fill up the entire space of the opening sediment.

6, but is of such width at its top surface as to leave two uninterrupted openings l0 10 around the top of .the burner for the exit of the gas and at which openings the gas is lighted. The edges of the cap are also vertical and parallel with the corresponding edges of the opening 6, so that the two uninterrupted openings both open directly upward. The

cap may also be provided with one or more str'uct-ion is objectionable owing to the fact.

that theseperforations soon become clogged up, requiring frequent cleaning, and, besides, in such form of burner it is absolutely impossible to .obtain access to the interior of the chamber in order to remove dirt, soot, and By my construction, however, thesedisadvantages are effectually obviated, and at the same time better flame-openings are provided than is afiorded by small apertures; also, by providing two uninterrupted flame-apertures perfect combustion is necessarily obtained.

The burner is also perfectly jointless, so that there is no opportunity for gas to escape. From the fact that perfect combustion is secured and also the escape of gas effectually guarded against the economical feature of the burner is apparent.

Attention is also called to the fact that by reason of the provision of two uninterrupted openings which open directly upwardly the bottom of a utensil above the jets of flame will secure the full benefit thereof, and the flame will not in the first instance be flared out around the sides of the utensil, as is the case with the ordinary form of burners.

I do not wish to be understood as confining myself to the particular shape of burner herein shown and described, inasmuch as it is obvious that said burner need not necessarily be of annular formas, for instance,it might be square, rectangular, oblong, or any other form, so long as a central opening is left which is bordered by the walls of the burner.

I also do not 'wish to confine myself to the particular V-shaped formation in cross-section of the cap, as it is obvious that said cap could be in the form of a flat plate and be just as conveniently supported within the opening of the chamber. The V-shaped formation, however, is preferable, inasmuch as it forms converging sides to the top, which sides are better adapted to permit the gas to pass up to the respective exit-openings 10 and 10.

Vhere the top is supported by means of depending legs, as shown, I do not wish to confine myself to a continuous groove for receiving said legs, inasmuch as simplya series of short grooves may be provided correspond ing in number to the number of legs employed, or any other desirable and convenient means for preventing lateral or sidewise movement of the legs or cap. The continuous groove or recess, however, is preferable, inasmuch as the top may be adjusted to place without the necessity of bringing it to a certain position in order to permit the legs to pass into their respective grooves or recesses where a plurality of such grooves or recesses are employed.

The depending legs as a support for the removable cap possess a distinct advantage, in-

asmuch as they in no manner interfere with or interrupt the free How of the gas to the openings 10 10, and by fitting the lower ends of the legs in the groove or gro'ovcs the cappiece is properly positioned to leave the proper width of openings 10 and 10.

Vhat I claim as my invention is- 1. In a gas-burner, the combination, of a chamber provided with a top opening, a cap fitted in, but of less width than,said opening, so as to leave uninterrupted inner and outer passages for the exit of the gas, said cap provided With depending legs extending to and adapted to be supported by the bottom of the chamber, and means for preventing lateral or sidewise movement of the legs or cap.

2. In a gas-burner, the combination, with a chamber provided in its bottom with a groove or grooves and having an opening in its top, ofa cap supported in, but of less width than,said opening so as to leave uninterrupted inner and outer passages for the exit of the gas, said cap provided with depending legs adapted to fit the groove or grooves in the bottom of the chamber.

In testimony whereof I affix my signature in presence of two witnesses.

MARTIN A. TIIIEL.
